摘要
根据对蟠龙油田上百口井的单井相分析及数十口井化验分析资料的分析结果,该区三叠系延长组 长2储层岩性主要为一套浅灰色细粒长石砂岩和细-中粒长石砂岩,砂体主要为辫状河流相沉积。其中长 21油层亚组发育两条河道,长22油层亚组发育两条主河道和一条次级河道。控油规律分析表明,沉积相 对该区长2油藏的形成和油水分布具有一定的控制作用,但不是唯一控油因素。
Based on the analyses of sedimentary facie of more than one hundred of wells and lots of experimental data of tens of wells, it can be concluded that the Chang 2 oil-bearing stratum of the Triassic Yangchang Formation in Panglong Oilfield is mainly grayish fine and fine-medium sandstones and the sandbodies are mainly deposits of braided streams. There are two main streams in Chang 21 sand bed. two main streams and one sub-stream in Chang2. it can be found that sedimentary facies in the study area have certa...
